The hex color #171F3D, often referred to as Big Stone, presents some accessibility challenges, particularly in text-based applications. Its low luminance value of approximately 4.4 cd/m² results in a low contrast ratio against standard white backgrounds. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text to ensure readability for users with visual impairments. Using #171F3D as text on a white background would likely fail these criteria. To improve accessibility, consider using it sparingly for purely decorative elements or pair it with lighter hues to achieve an adequate contrast ratio. Additionally, providing alternative text descriptions for any images or graphical elements using this color is essential for users who rely on screen readers. Testing the color combination with accessibility evaluation tools is highly recommended to ensure compliance with accessibility standards.
